I just installed Beyond Good and Evil on a Mac using Crossover Games 7.2. It looks like the game is fully playable, with some minor issues:
- You have to turn shadows off in the configuration panel, or Jade (and seemingly only Jade) will appear only as a black silhouette
- The first video in the game is upside down (it only lasts a few seconds). I'm not sure if the other "videos" I saw were real videos or animations made with the game engine, but the problem seemed to be fixed after this.
- One of the songs (after you pay the bill to turn the lights on) looped weirdly.
- Some of the dialogue didn't seem to play correctly (or was I expecting a voiceover when there wasn't one?)
I didn't play the game natively under Windows yet, so I don't know if its textures are displaying correctly, if all of the detail is there, etc. My guess is that it is fully playable but that there are certainly some minor issues and glitches.
